I get the feeling more people are comfortable contributing to their own 3rd
party CI then upstream openstack CI systems.  Either because they don't have the
time or don't understand how it works. I agree with Doug, for this to work, I
think we need to have a health amount of people helping keep the CI systems
running upstream, then depending on 3rd party CI downstream.

As a comment, I think getting involved in the openstack-stablemaint team will be
a good first step towards the goals people are interested in here. I'm happy to
help work with others, and I'm taking tonyb up on his offer to start helping too
